Kepler 298 d was opened in 2014 [1] . It was assumed that this exoplanet revolves around the mother star inside its habitable zone by analogy with Tau Ceti e . The Kepler 298 d was calculated to be an earth-like planet, but further studies showed that its atmosphere is gaining +2.11 on the HZA scale, which means that it can be an ocean-type planet with a thick atmosphere similar to the atmosphere of gas giants . It is also possible that exoplanet is a super-Venus .
